Rogaine contains minoxidil, an ingredient that stimulates shrunken hair follicles and encourages new hair growth, explains Rogaine. Within two weeks of applying the treatment, it is common for users to experience shedding of older, thinner hairs. Once the thin hairs have been shed, the medication works to expand the side of the hair follicles, resulting in thicker hair growth. It can take up to four months for new hair to grow in when the treatment is used as directed.
